  case 'get_email': {
    const args = GetEmailSchema.parse(request.params.arguments);
    const result = await this.hubspot.getEmail(args.emailId);
    return {
      content: [{ type: 'text', text: JSON.stringify(result, null, 2) }],
    };
  }

• src/tools/types.ts:9-11 (schema)

  Zod schema definition for get_email tool input validation, requiring an emailId string parameter

  export const GetEmailSchema = z.object({
    emailId: z.string(),
  });

    inputSchema: {
      type: 'object',

        emailId: { type: 'string', description: 'メールID' },
      },
      required: ['emailId'],
